In a Nutshell

I called this web site “AQUESTIONOFTIME.COM” since that is the essence of the issue in Einstein’s Theory of Special Relativity, SRT 1905.

Einstein’s Special Relativity Theory, SRT 1905, is founded on his conviction that time is relative, i.e. two observers on different bodies, that are in relative motion, cannot synchronize their clocks. We begin by showing that it is possible to synchronize two such clocks by making use of the Doppler effect. Without the relativity of time, SRT, and all that it implies about cosmology and astrophysics, loses its relevance as a credible scientific endeavour.

Prologue:

There are two kinds of errors that can invalidate a mathematical theory about the character of the universe:
(1) An error in a calculation, that can later be corrected.

(2) An error in basic premises that can be shown to be false. This type of error
cannot be corrected, and if sufficiently grave invalidates the entire theory.

Lorentz made an error of the first type, while Einstein made an error of the second
type
